What is a Magnet Valve and how does it work?

- 2024-12-11-

‌Magnet Valve‌ is an industrial equipment that uses electromagnetic control. It is mainly used to control the basic automation components of fluids and belongs to actuators. It controls the direction, flow, speed and other parameters of the fluid through electromagnetic force, and is widely used in various industrial control systems and mechanical equipment‌.

Working principle of Magnet Valve

The Magnet Valve is mainly composed of valve body, electromagnetic coil, iron core and armature. When the electromagnetic coil is energized, magnetic force will be generated, which will act on the armature to push the valve core to move, thereby opening or closing the fluid channel. When the electromagnetic coil is de-energized, the valve core is reset under the action of spring force to close the fluid channel‌.


Classification of Magnet Valves


Magnet Valves can be divided into two categories:

Direct-acting Magnet Valve‌: When the coil is energized, the valve is directly opened or closed.

‌Pilot Magnet Valve‌: When energized, the valve gradually opens or closes according to the size of the pressure difference‌.


In addition, Magnet Valves also have two types: normally closed (NC) and normally open (NO):

‌Normal closed Magnet Valve (NC): the valve core is closed when the coil is not energized, and opens when energized.

‌Normal open Magnet Valve (NO): the valve core opens when the coil is de-energized, and closes when energized.

Application scenarios of Magnet Valves


Magnet Valves are widely used in various industrial control systems and mechanical equipment, such as:

‌Hydraulic system‌: control the direction and flow of hydraulic oil.

‌Pneumatic system‌: control the on and off of gas.

‌Refrigeration system‌: used for loading and unloading, adjusting capacity, defrosting and refrigeration conversion, etc.
